Hammock and nesting in preterm infants: randomized controlled trial

Abstract

Objective: To compare the physiological variables and the sleep-wake pattern presented by preterm in nesting and hammock positions after diaper change.

Method: This is a crossover randomized controlled trial. It was conducted with 20 preterm infants who, after diaper change, were placed in nests or hammocks. These preterm infants were evaluated for physiological variables (heart rate and oxygen saturation) and behavioral variables (sleep and wakefulness).

Results: There was no statistically significant difference in the studied variables between nesting and hammock positions. However, regarding the categorical variable sleep, the comparison between the research phases for the hammock position showed differences between the baseline phase and the immediate recovery (p=0.00), baseline and late recovery (p=0.00), response and immediate recovery (p=0.00), response and late recovery (p=0.00).

Conclusion: No differences were identified between the nest and the hammock; however, the use of the hammock favored the sleep of preterm infants compared to its non-use.
